It was too bad that we did not have more time to spend with one another today on Math. Since I do not have a Google Classroom anymore, I will slowly get back into the habit of posting on my blog.
In the case of today's lesson on subtracting integers, I will post the following information:
First, here is a review of negative numbers from an old friend.
Here is a longer video you can look at. You can "chunk" it and break it into pieces and watch a little bit at a time. There is a lot of information here about the adding and subtraction of integers.
Thanks to one of my SSTC colleagues -- Stephanie -- for pointing out this video to me. It goes a little too quick for my liking and doesn't slow down enough to explain what is happening, but it demonstrated the "zero pairs" concept using these toy soldiers.
After today's lesson, I hope you are clearer about how you can use the number line to help you solve subtracting questions. You will see, from the chart up in the class (which I will take a photo of), we solved questions using the number line and what we called the "inverse method." I hope you will continue to practice it. Below, the concept is demonstrated in a video using integer chips.
Danielle Krueger, a YouTuber has a couple of really great videos using counters to explaining adding and subtracting. Since we are discussing subtraction, here it is first. I will place the addition and the multiplication one right after.

Games! These are only a couple of many games that will help you reinforce some of the skills you are working on in class.
This game can be played in partners and uses the idea of the Connect Four game.
